SELF-CLOSING PAPER-BAG MACHENE.

Specification of Letters Patent.-

Patented June 5, 1906.

To all whom it may concern:

Be it known that I, ODILON DESROSIERS, a subject of the King of Great Britain and Ireland, residin in the town of Louiseville, in the county ofMaskinong, in the Province of Quebec, Canada, have invented a new and useful Self-Closing Paper-Bag Machine, of which the following is a specification.

The invention refers to a machine to paste the wires on the self-closing device for paper bags, and the object is obtained by fastening with paste across the length of the ba near the mouth thereof strips of paper or fa%ric such as cotton, linen, canvas, and the like-'- doubled overv a metal Wire and extending beyond the Width of the bag in such a manner that the bag may be closed by folding over the mouth two or three times and bending or twisting the ends of the wire and ribbon projecting out beyond their width.

.The invention consists of a frame supporting the parts, an endless apron, and at one end of the frame one or two reels containing eacha long ribbon of paper or fabric about five-eighths of an inch in width, one of these reels bein situated above the apron and the other undhrneath. These ribbons of paper or of fabric are drawn toward the other end of the machine by proper gearing. (Not shown on the drawings.) As the ribbons travel toward the other end they receive along their center a continuous stri e of paste, and they are made to pass into a fhlder which longitudinally doubles them over a metal wire carried along with it until the folded ribbons and the wire therein contained come over one another between two rubber rollers. While the ribbons and the wires are thus moving, the bags held flat, one on each section of the endless apron, travel toward the two rubber rollers, receiving on their way transversally to their length and near the edges of their mouth on each side thereof a stripe of paste, so that the stripe of paste comes to the rubber rollers between the two ribbons. The action of the rubberrollers pressing on the whole fastens the ribbons to the bags. The whole emerges from the pressing-rollers to come between two wheels containing sets of knives, which cut the ribbons and their wires aboutan inch beyond the edges of the bag.

Wire-reels situated at the rear feed the wires through the shaft or axle of the grooved wheels nearest to the folders.

The accompanying drawings illustrate the invention.

Figure 1 is an elevation of the side of the machine opposite the working side. Fig. 2 is a plan of the machine. Fig. 3 is a front view of the folder opened. Fig. 4 is an elevation of the Wide end or inlet of the same.

A is the frame supporting all the parts of the mechanism.

B B are the sections of the endless apron rolling over the parallel wheels 14 and 15, the upper surface thereof moving toward 14, each section of the apron bein slightly longer than the width of the bags an narrower than the length of the bags to be laid across the apron.

C C is the endless chain of the apron.

a, is the lower piece of the folder; I) the upper piece of the same.

0 is the tongue on which the ribbon. is doubled over the wire which passes through the hole 1.

d is a hole in the end of the tongue 0, through which the wire is fed to the pasted ribbon which is to cover it.

e e are two guides in the inlet or large end of the folder to keep the ribbon in a vertical position.

f indicates the hinges of the folder, which may be opened whenrequired.

g is the outlet of the folder, where the ribbon folded over the wire is made to pass, pressed so as to fasten the ribbon on the wire.

1 1 1 are small lugs fixed to the latter end uides and holes in the end of of each section of the endless apron, so as to keep the paper bags square across the apron and secure their coming to the pressing-rollers 12 12 in a true transversal position.

2 is a spring-finger fastened on the arm 16 and pressing i htly on the apron, so as to place the paperiags close against the lugs 1 1.

3 3 are strips of metal also fastened to the arm 16 and extendin the whole length of the apron to steady the age in their position on the sections.

4 is the u per reel containing the ribbon to be fed and dbubled over a wire and pasted on the upper face of the folded bag.

' 4'? is another reel situated under the frame to feed out the ribbon to be doubled over a and transversally at the mouth of the bags.

6 6 are ribbons-pasting wheels turning partly in troughs containing paste to de osit a stripeof the same on the under face 0 the ribbons. 7 7 are gages of suitable material held to the edge of the troughs, so as to remove from the wheels the useless quantity of paste. They fit close tothe side of the 'Wheels, but may be adjusted more or less close to the periphery, according to the thickness of paste required on the ribbons or on the bag.

88 are grooved wheels proportionate to the width of the ribbons, the object of which is to maintain the ribbon over the asting-wheels.

9 9 are the wedge-shape fo ders hereinbefore described.

10 10, 11 1-1 are sets of rubber rollers to press the ribbons folded over the wire and insure their adherence.

1'2 12 are two 1 rubber rollers to press and fasten the ribbons doubled over the wires onto the paper bags.

13, 13am two wheels carrying knives evenly distanced across their periphery to .cut the ribbons and the wire contained therein about one inch beyond each'side of the bag.

14 and 1 5,- are two parallel wheels over which the endless apron rolls.

16 is an arm held to the frame and extendingtransversally over the apron so as to hold in position the two long bands 3 3 and the spring-finger 2.

17 is a guard-rail extending the whole length of the apronto prevent the bags from slidingout of their place on the sections of the apron.

18 is another guardrail on the far side of the apronfor the same urpose as the first. It extends as far as whee 20.

19 19 are the knives evenly distanced across the periphery of the wheels 13.

20 is a pasting-wheel .turning partly in the paste contained in the trough and transfer-1 ring the paste to wheel 21, which is to lay the itripe of paste on the upper side of the folded 22 is another pasting-wheel similar to wheel' 20 to deposit a stripe of paste on the lower side of the folded bag.

24 and 25 are the ribbons traveling toward the folder.

26 is' a rubber-tired-wheel supporting the lower part of the apron.

27 is a double reel containing two rolls of wire, one of which feeds the wire to the upper folder and the other to the lower folder.

28 is the Wire passing through a hole horizontally made in the end of the rigid axle of the grooved wheel 8, thence to the hole d of the tongue 0 of the upper folder.

29 is the other wire passing through guides onto a horizontal hole in the end of axle of wheel 8, thence to the lower folder.

The power is ap lied on the axle of the parallel wheel 14 an through suitable gearing (not shown in drawings) located on the far side of the machine. The speed of all these wheels is regulated so that they all work together.

To utilize the invention, the machine is set going and the apron moves from right to left,

and all the wheels turn in the direction to draw the ribbons, wires, and bags toward the left. The end of the ribbons is placed horizontally in the groove of the guide-wheels 8 and over the paste-wheels 6, where they receive a longitudinal stripe of paste. Thence they enter vertically into the inlet of the folders 9 9. At the same time the end of the wire is introduced in the hole in the end of the axleof the grooved wheels, thence into the hole d of the tongue 0 of the folders, and ribbons and.

wires are pulled between the press-wheels 10 10 and 1 1 11, where the ribbons are made fast on the wire,thence onto the grooved wheels 8 8.

The bags, folded flat, as they come from factories, are fed on the sections of the endless apron. As they pass under the spring-finger 2, attached to the arm 16, they are pressed against the lugs I I, located at the latter end of each section and held there by the two strips of metal 3 3, extending all along the upper face of the apron. On their way the bags pass between the two paste-wheels 21 and 22,

where ,they receive transversally to their length two narrow stripes of paste. Thence they consecutively reach the two press-wheels 1 2 12 between the ribbons containing the wire, which are pressed on the stripe of paste of the bags and rmly united thereto. The whole emerges from there to meet the knives of the cutting-wheels where the ribbons and their wires are out, leaving the two ends projecting out on each side of the bags, and they fall ready for use.

I will not claim as my invention the paper bags nor the device for self-closing bags, as they are the matter of patents already granted; but

What I claim, and desire to secure by Letters Patent, is-

In self-closing paper-bag machines: a frame to support the parts, an endless apron to convey the paper bags, each section thereof having lugs at the rear end to insure the progress of the bags toward the knives, a spring-finger to place thebags close against the lugs of the 1 bled over in the ribbons and pasted on each fasten the ribbons on the stripes of paste, at side of the bag; folders having therein guides the mouth of the bags and a set of knives to to keep the ribbonsin a vertical position and a cut the ribbons and wires, a little beyond the tongue, transverselly to their length, to double width of the bags, in the manner and for the I 5 over the ribbons and having a hole horizonpurpose hereinebove mentioned.
